Be it known that I, BERNARD M. McFAn- LANE, a citizen of the UnitedStates, residing at Hettinger, in the county of Adams, State of NorthDakota, have invented certain new and useful Improvements in Binder Ele*vators; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as Vwill enable others l0skilled in the art to which it appertains to make and use the same.

rilhis invention relates to grain binders, and more especially to thatclass of devices known as endless belt loaders; and the obf' jectof thesame is to produce a simple forni of elevator mechanism which can beapplied to the binder by first removing certain parts of the latter, andisserviceable for carrying grain from the table of the binder to theheader box. p

The invention includes an elevator consisting of an ordinary endlesscanvas belt or apron with slats, but it has specially constructed sidesandftop for holding the grain in place on the upper stretch of theapron,

yielding when necessary, and preventing the .action of wind thereon, andit has means whereby the upper end of the entire elevator may be raisedor lowered or held at any desired height.

t is my purpose to produce a cheap and serviceable article of thischaracter which can be sold to the farmer and by him ap-y plied to astandard make of binding inachine.

The following specification sets forth one successful embodiment of theidea, reference being had tothe drawings in which:

Figure l is a perspective View of this device complete, indicating `indotted linen a power chain applied to its driving sprocket and a ropeattached to its bail. v

Figure 2 is a cross section on the line 2 2 of Figure l.

Figure 3 is a longitudinal section.

The frame 0f this elevator includes rather wide upright sides lconnected by a bottom board 2 at their lower ends and by a wider bottomboard 3 at their upper ends, and the upper edges of the side boards arepreferably also connected by straps 4t at their upper and lower ends. Aroller 5 has truniiions 6 journaled in bearingsifat the lower ends ofthe sides, and fonefof .said truunions has ay sprocket wheel I to whicha power lchain may be applied asseen in dotted lines. similar rollerhas'its Atiunnions 8 yournaled inthe side boards near their lupperends."` `lrround these rollers .nioves an endless canvas'belt or apronQhaving slats l() secured acrossits outer face at inter vals, and thechain and sprocket will vcause the upper stretch of this apron tomoveupward between the si'des,'which latter will prevent a lateral blast ofwindv from striking the grain which lies on the elevator.

Supported1 `at 20 in theside boardsvfnear their lower ends is a rockablecross bai"21 carrying a seriesof vretainerbars 22"extend= inglongitudinally within theJ `frame and standing parallel vwith and.rather close vto each other, and the uppery ends of these ref` i itainerbars are supportedy by a notched bar or combl 23 whose back 24extends across between the side boards near their upper ends and whoseteeth which are flattened at their lower ends, are spaced to correspondwith the spacing of the retainer bars and have the upper ends of saidretainer bars attached thereto, leaving the spaces between the teethalining with the spaces between the retainer bars'. At each endof thecomb is attached a flexible element such as a strap 25 which leads overthe upper edge of a side board and is secured to the outer side of thesame as at 26. These straps prevent the comb from falling to such adistance as to permit the upper ends of the slats to stand undesirablyclose to the cross slats on the apron, while at the same time the strapspermit thev comb and the upper ends of tached, as shown in dotted linesin Figure The upper edges of` l, the same serving as vmeans foradjusting the upper end of the elevator to any desired position andholding it there.

In applying this device to an ordinary binding machine, the bindingparts of the latter are removed and theelevatorattached,

its sprocket being connected with the saine chain that drives the lowerelevator on said machine.v The upper end of the elevator is now adjustedso as to lead 'to the header box. The grain cut by the machine isdelivered to the lower end of the elevator and onto its apron or beltbeneath the retainer'bars 22, and the apron carries or elevates thegrain and ldelivers it to said box. In its passage upward on the upperstretch of the apron,

it is held thereon by the retainer bars' andv moves beneath them, andany pieces of grain which project between the retainer bars will movethrough the spaces between the comb teeth. The weight of the comb addedto that of the upper ends of the retainer bars holds the latter down'onto the grain and the grain down on'the apron, but the flexiblelconnection or straps 25 permit the comb and retainer bars to riseincase the'accumu lation of grain is sufficient, andthus thev choking orcloggrgiiigg of the elevator at its outlet end is prevented. Theopening'at the bottombetweenthe bottom boards 2 and 3 permits thedropping out of whatever is carried over the upper roller by the apron,and thus the choking and clogging oi" the lower stretch ofI the elevatoris prevented. While my invention is primarily intended` for aiise suchas has'been described7 l do notv wish to be limited to that particularuse.

Also, while have describedI and shown a canvas apron with cross slats, lclaim no novelty for this detail.

What is claimed is:

A binder elevator including` a frame, an endless belt mounted in theframe, a'transverse bar rotatably mounted in the sides of the lowerportion of the frame for rocking movement, a transverse bar extendingbetween the sides of the upper end of the frame, flexible straps securedto the ends of the last-named bar and to the sides oi? the frame toperinitthe bar to rise and fall under the influence of material passingthereunder and to maintain said bar in spaced relation with respect toand above said belt, the lower portion of the upper bar being formedwith a longitudinal series of depending; teeth each having its lower endlattened, and retainer bars extending longitudinally of the frame andover the endless belt with their upper ends secured to the saidflattened ends of' the teeth of the upper bar and their lower endssecured to the lower 'face oi the rocking,l bar 'for rocking movenienttherewith.

In testimony whereof, I affix niy signature,'in the presence of twowitnesses.
